Associating requests for content with a confirmed location

ABSTRACT

Methods, systems, and apparatus include computer programs encoded on a computer-readable storage medium, including a method for providing content. A first confirmation is received of a location associated with a user identifier. A confirmed location identifies a physical address of a user device associated with the user identifier. Subsequent to the first confirmation, location data associated with a user device associated with the user identifier is processed, including determining that the user device is near the confirmed location. A second confirmation confirms that sufficient occurrences have identified of a presence of a device associated with the user identifier near the confirmed location. Characteristics of an environment accessed by the user are determined and stored in association with the confirmed location. Requests are received from other users. Characteristics of a given request are compared with stored characteristics. When comparing indicates a match, the confirmed location is associated with the subsequent request.

BACKGROUND

This specification relates to information presentation.

The Internet provides access to a wide variety of resources. For example, video and/or audio files, as well as webpages for particular subjects or particular news articles, are accessible over the Internet. Access to these resources presents opportunities for other content (e.g., advertisements) to be provided with the resources. For example, a webpage can include slots in which content can be presented. These slots can be defined in the webpage or defined for presentation with a webpage, for example, along with search results. Content in these examples can be of various formats, while the devices that consume (e.g., present) the content can be equally varied in terms of their type and capabilities.

Content slots can be allocated to content sponsors as part of a reservation system, or in an auction. For example, content sponsors can provide bids specifying amounts that the sponsors are respectively willing to pay for presentation of their content. In turn, an auction can be run, and the slots can be allocated to sponsors according, among other things, to their bids and/or a likelihood that the user will interact with the content presented.

SUMMARY

In general, one innovative aspect of the subject matter described in this specification can be implemented in methods that include a computer-implemented method for providing content. The method includes receiving a user identifier associated with a user. The method further includes receiving a first confirmation of a location associated with the user identifier including identifying a confirmed location, wherein the confirmed location includes a physical address that is associated with the user identifier, and wherein the receiving includes receiving a type of location. The method further includes, subsequent to receiving the first confirmation, processing location data associated with a user device associated with the user identifier, including determining that the user device is in a vicinity of the confirmed location. The method further includes performing, using one or more processors, a second confirmation including, based on the processing, confirming that a sufficient number of occurrences have been identified of a presence of a device associated with the user identifier in the vicinity of the confirmed location. The method further includes determining one or more characteristics of an environment accessed by the user in association with a presence at a confirmed location. The method further includes storing the one or more characteristics of the environment in association with the confirmed location. The method further includes subsequent to the storing, comparing the stored one or more characteristics with one or more characteristics of a subsequent request from a user device associated with another user identifier. The method further includes, when the comparing indicates a match, associating the confirmed location with the subsequent request.

These and other implementations can each optionally include one or more of the following features. Processing location data can include receiving location data from the user when the user is logged in, and the location data can be received through a wireless network. Confirming a sufficient number of occurrences can include determining a plurality of occurrences of the presence of the user are received from a location in the vicinity to the confirmed location based on a network identifier for a wireless network and one or more network signal quality metrics associated with a received request. The network identifier can be a service set identifier (SSID) or a media access control (MAC) address, and the one or more network signal quality metrics can include a signal strength. Determining the one or more characteristics can include identifying signal strength and wireless network identifier information. Associating the confirmed location can further include using the confirmed location for selecting content to provide in response to the subsequent request. The second confirmation can include determining signal strength of a wireless signal associated with a signal that includes the location data, comparing the signal strength to a threshold, and when the signal strength exceeds the threshold, storing a network identifier for the wireless network associated with wireless signal in association with the confirmed location. Storing the characteristics can include storing a confirmed location and a network identifier for the wireless network. Associating the confirmed location with the subsequent request can include identifying an entity associating with the confirmed location and associating the identified entity with the subsequent request. The entity can be a business and the confirmed location can be a brick-and-mortar location associated with the entity.

In general, another innovative aspect of the subject matter described in this specification can be implemented in computer program products that include a computer program product tangibly embodied in a computer-readable storage device and comprising instructions. The instructions, when executed by one or more processors, cause the processor to: receive a first confirmation of a location associated with the user identifier including identifying a confirmed location, wherein athe confirmed location includes a physical address that is associated with the user identifier, and wherein the receiving includes receiving a type of location; subsequent to receiving the first confirmation, process location data associated with a user device associated with the user identifier, including determining that the user device is in a vicinity of the confirmed location; perform a second confirmation including, based on the processing, confirming that a sufficient number of occurrences have been identified of a presence of a device associated with the user identifier in the vicinity of the confirmed location; determine one or more characteristics of an environment accessed by the user in association with a presence at a confirmed location; store the one or more characteristics of the environment in association with the confirmed location; subsequent to the storing, compare the stored one or more characteristics with one or more characteristics of a subsequent request from a user device associated with another user identifier; and when the comparing indicates a match, associate the confirmed location with the subsequent request.

These and other implementations can each optionally include one or more of the following features. Processing location data can include receiving location data from the user when the user is logged in, and the location data can be received through a wireless network. Confirming a sufficient number of occurrences can include determining a plurality of occurrences of the presence of the user are received from a location in the vicinity to the confirmed location based on a network identifier for a wireless network and one or more network signal quality metrics associated with a received request. The network identifier can be a service set identifier (SSID) or a media access control (MAC) address, and the one or more network signal quality metrics can include a signal strength. Associating the confirmed location can further include using the confirmed location for selecting content to provide in response to the subsequent request.

In general, another innovative aspect of the subject matter described in this specification can be implemented in systems, including a system comprising one or more processors and one or more memory elements including instructions. The instructions, when executed, cause the one or more processors to: receive a first confirmation of a location associated with the user identifier including identifying a confirmed location, wherein athe confirmed location includes a physical address that is associated with the user identifier, and wherein the receiving includes receiving a type of location; subsequent to receiving the first confirmation, process location data associated with a user device associated with the user identifier, including determining that the user device is in a vicinity of the confirmed location; perform a second confirmation including, based on the processing, confirming that a sufficient number of occurrences have been identified of a presence of a device associated with the user identifier in the vicinity of the confirmed location; determine one or more characteristics of an environment accessed by the user in association with a presence at a confirmed location; store the one or more characteristics of the environment in association with the confirmed location; subsequent to the storing, compare the stored one or more characteristics with one or more characteristics of a subsequent request from a user device associated with another user identifier; and when the comparing indicates a match, associate the confirmed location with the subsequent request.

These and other implementations can each optionally include one or more of the following features. Processing location data can include receiving location data from the user when the user is logged in, and the location data can be received through a wireless network. Confirming a sufficient number of occurrences can include determining a plurality of occurrences of the presence of the user are received from a location in the vicinity to the confirmed location based on a network identifier for a wireless network and one or more network signal quality metrics associated with a received request. The network identifier can be a service set identifier (SSID) or a media access control (MAC) address, and the one or more network signal quality metrics can include a signal strength. Associating the confirmed location can further include using the confirmed location for selecting content to provide in response to the subsequent request.

Particular implementations may realize none, one or more of the following advantages. User identifiers associated with users can be determined as being present in a confirmed location when environmental characteristics (e.g., network information) associated with the users' network access can be matched to environmental characteristics of a confirmed location identified previously, e.g., by a first user.

The details of one or more implementations of the subject matter described in this specification are set forth in the accompanying drawings and the description below. Other features, aspects, and advantages of the subject matter will become apparent from the description, the drawings, and the claims.

DETAILED DESCRIPTION

Systems, methods, and computer program products are described for associating received requests from users with a particular confirmed location (e.g., of a first user). For example, a first user accessing a network (e.g., a particular WiFi network) can identify a particular location associated with the accessing (e.g., a workplace or home setting). Subsequently, repeated occurrences can be logged of the first user using the same network for the confirmed location. Environment characteristics, including network identifiers, can be stored in association with the confirmed location. Requests (e.g., requests for content) received from other users can also include environment characteristics. When it is determined that the environment characteristics of the received requests match the environment characteristics that are associated with the confirmed location, then the received requests can also be associated with the confirmed location, even when such requests are from other different users. The associations can be used, for example, when selecting content to be provided responsive to the requests or used for other reasons.

For situations in which the systems discussed here collect and/or use personal information about users, the users may be provided with an opportunity to enable/disable or control programs or features that may collect and/or use personal information (e.g., information about a user's social network, social actions or activities, a user's preferences or a user's current location). In addition, certain data may be treated in one or more ways before it is stored or used, so that personally identifiable information associated with the user is removed. For example, a user's identity may be anonymized so that the no personally identifiable information can be determined for the user, or a user's geographic location may be generalized where location information is obtained (such as to a city, ZIP code, or state level), so that a particular location of a user cannot be determined.

FIG. 1 is a block diagram of an example environment 100 for providing content. The example environment 100 includes a content management system 110 for selecting and providing content in response to requests for content. The example environment 100 includes a network 102, such as a local area network (LAN), a wide area network (WAN), the Internet, or a combination thereof. The network 102 connects websites 104 (e.g., addressable resources), user devices 106, content sponsors 108 (e.g., advertisers), publishers 109, and the content management system 110. The example environment 100 may include many thousands of websites 104, user devices 106, content sponsors 108 and publishers 109.

The environment 100 can include plural data stores, which can be stored locally by the content management system 110, stored somewhere else and accessible using the network 102, generated as needed from various data sources, or some combination of these. Further, some data stores described herein may include identifiers that can be used to match or access corresponding data records or other information that are stored elsewhere, e.g. locally and/or remotely.

A data store of location associations 132, for example, can store information that associates a user identifier with an identified location. For example, the identified location can include, for example, a physical address of a location that the user designates as a workplace location, a home location, or some other physical location.

A data store of device locations 134, for example, can include information on a device basis (e.g., by device ID) that identifies a location associated with a device. For example, the information can indicate that the user's workplace computer, having a particular device identifier, is associated with the user's workplace and corresponding physical address.

A data store of confirmed locations 136, for example, can include information indicating a physical location at which a user device having a user identifier is confirmed to have been present on a number of occurrences. For example, a confirmed location can be a brick-and-mortar location, such as the user's workplace, home, or another physical location at which the user device having the user identifier is or has been present.

A data store of environment characteristics 138, for example, can include information for characteristics of an environment associated with a user, or for a user device associated with the user identifier. For example, characteristics can be included with requests that are received from users, or included with received location information associated with users. Characteristics can include, for example, network information, such as network identifiers associated with wireless networks. Characteristics can also include one or more network signal quality metrics, such as signal strength.

The content management system 110 can include plural engines, some or all of which may be combined or separate, and may be co-located or distributed (e.g., connected over the network 102). A location association engine 122, for example, can identify the first user and receive confirmation of a location that is associated with the user identifier. The location confirmation can also include information that identifies the location's type (e.g., a work location), such as if the first user 202 a indicates that the user device 106 a is situated at the user's workplace (e.g., the confirmed location 208).

A device location engine 124, for example, can process device location data associated with a user device and determine whether or not the user device is in a vicinity of a confirmed location. For example, the determining can include determining that the user device 106 a is networked through a particular network (e.g., a WiFi network) of the confirmed location and whether the associated signal strength meets a minimum threshold signal strength.

A location determination engine 126, for example, can use location information processed from a user device to confirm that a sufficient number of occurrences have been identified to confirm a presence of the user device (and associated user) in a vicinity of the location. The location determination engine 126 can also receive or determine environment characteristics (e.g., a network identifier of wireless network) in association with the location information, e.g., for subsequent use in determining that other users' user devices are in the same vicinity. In some implementations, global positioning system (GPS) capabilities of the user device can provide location information (e.g., a geographic location) associated with the user identifier, e.g., that the location determination engine 126 can use to confirm a presence of the user device in a vicinity of the location.

A website 104 includes one or more resources 105 associated with a domain name and hosted by one or more servers. An example website is a collection of webpages formatted in hypertext markup language (HTML) that can contain text, images, multimedia content, and programming elements, such as scripts. Each website 104 can be maintained by a content publisher, which is an entity that controls, manages and/or owns the website 104.

A resource 105 can be any data that can be provided over the network 102. A resource 105 can be identified by a resource address that is associated with the resource 105. Resources include HTML pages, word processing documents, portable document format (PDF) documents, images, video, and news feed sources, to name only a few. The resources can include content, such as words, phrases, images, video and sounds, that may include embedded information (such as meta-information hyperlinks) and/or embedded instructions (such as JavaScript™ scripts).

A user device 106 is an electronic device that is under control of a user and is capable of requesting and receiving resources over the network 102. Example user devices 106 include personal computers (PCs), televisions with one or more processors embedded therein or coupled thereto, set-top boxes, gaming consoles, mobile communication devices (e.g., smartphones), tablet computers and other devices that can send and receive data over the network 102. A user device 106 typically includes one or more user applications, such as a web browser, to facilitate the sending and receiving of data over the network 102.

A user device 106 can request resources 105 from a website 104. In turn, data representing the resource 105 can be provided to the user device 106 for presentation by the user device 106. The data representing the resource 105 can also include data specifying a portion of the resource or a portion of a user display, such as a presentation location of a pop-up window or a slot of a third-party content site or webpage, in which content can be presented. These specified portions of the resource or user display are referred to as slots (e.g., ad slots).

To facilitate searching of these resources, the environment 100 can include a search system 112 that identifies the resources by crawling and indexing the resources provided by the content publishers on the websites 104. Data about the resources can be indexed based on the resource to which the data corresponds. The indexed and, optionally, cached copies of the resources can be stored in an indexed cache 114.

User devices 106 can submit search queries 116 to the search system 112 over the network 102. In response, the search system 112 can, for example, access the indexed cache 114 to identify resources that are relevant to the search query 116. The search system 112 identifies the resources in the form of search results 118 and returns the search results 118 to the user devices 106 in search results pages. A search result 118 can be data generated by the search system 112 that identifies a resource that is provided in response to a particular search query, and includes a link to the resource. Search results pages can also include one or more slots in which other content items (e.g., advertisements) can be presented.

When a resource 105, search results 118 and/or other content (e.g., a video) are requested by a user device 106, the content management system 110 receives a request for content. The request for content can include characteristics of the slots that are defined for the requested resource or search results page, and can be provided to the content management system 110.

For example, a reference (e.g., URL) to the resource for which the slot is defined, a size of the slot, and/or media types that are available for presentation in the slot can be provided to the content management system 110 in association with a given request. Similarly, keywords associated with a requested resource (“resource keywords”) or a search query 116 for which search results are requested can also be provided to the content management system 110 to facilitate identification of content that is relevant to the resource or search query 116.

Based at least in part on data included in the request, the content management system 110 can select content that is eligible to be provided in response to the request (“eligible content items”). For example, eligible content items can include eligible ads having characteristics matching the characteristics of ad slots and that are identified as relevant to specified resource keywords or search queries 116. In addition, when no search is performed or no keywords are available (e.g., because the user is not browsing a webpage), other information, such as information obtained from one or more snapshots, can be used to respond to the received request. In some implementations, the selection of the eligible content items can further depend on user signals, such as demographic signals, behavioral signals or other signals derived from a user profile.

The content management system 110 can select from the eligible content items that are to be provided for presentation in slots of a resource or search results page based at least in part on results of an auction (or by some other selection process). For example, for the eligible content items, the content management system 110 can receive offers from content sponsors 108 and allocate the slots, based at least in part on the received offers (e.g., based on the highest bidders at the conclusion of the auction or based on other criteria, such as those related to satisfying open reservations and a value of learning). The offers represent the amounts that the content sponsors are willing to pay for presentation of (or selection of or other interaction with) their content with a resource or search results page. For example, an offer can specify an amount that a content sponsor is willing to pay for each 1000 impressions (i.e., presentations) of the content item, referred to as a CPM bid. Alternatively, the offer can specify an amount that the content sponsor is willing to pay (e.g., a cost per engagement) for a selection (i.e., a click-through) of the content item or a conversion following selection of the content item. For example, the selected content item can be determined based on the offers alone, or based on the offers of each content sponsor being multiplied by one or more factors, such as quality scores derived from content performance, landing page scores, a value of learning, and/or other factors.

A conversion can be said to occur when a user performs a particular transaction or action related to a content item provided with a resource or search results page. What constitutes a conversion may vary from case-to-case and can be determined in a variety of ways. For example, a conversion may occur when a user clicks on a content item (e.g., an ad), is referred to a webpage, and consummates a purchase there before leaving that webpage. A conversion can also be defined by a content provider to be any measurable or observable user action, such as downloading a white paper, navigating to at least a given depth of a website, viewing at least a certain number of webpages, spending at least a predetermined amount of time on a web site or webpage, registering on a website, experiencing media, or performing a social action regarding a content item (e.g., an ad), such as endorsing, republishing or sharing the content item. Other actions that constitute a conversion can also be used.

FIG. 2 shows an example system 200 for associating received requests from users with a particular confirmed location of a user identifier. For example, a user identifier associated with a first user 202 a can be associated with a confirmed location 208, e.g., the user's user-identified workplace. Confirmation can occur, for example, after repeated occurrences of use, by the first user 202 a, of a wireless network 217, e.g., WiFi with service set identifier (SSID) “A” that is located at the user's workplace. Requests 218 that are received from user devices 106 b (e.g., associated with other users 202 b) can also be associated with the same confirmed location 208. Associations that are made can be based, for example, on characteristics 220 received with the requests 218 that match environment characteristics 216 received with location information 214. In some implementations, the following example stages can be used for making the associations.

At stage 1, for example, the location association engine 122 can receive a user identifier associated with the first user 202 a. User identification 204 can include, for example, receiving a user identifier that is obtained when the first user 202 a uses an application running on the user device 106 a, through a user login service, a social network, or in some other way.

At stage 2a, for example, the location association engine 122 can receive location information 206 associated with the received user identifier (e.g., associated with first user 202 a). For example, user device location data can be determined based on location information derived from, or provided by, a user device associated with the received user identifier. At stage 2b, for example, the location information can be confirmed (207) by the first user 202 a, either explicitly or implicitly. For example, the first user 202 a may be prompted to confirm the location information (e.g., “is this your home or work or other location?”). The location information can be confirmed implicitly, such as by evaluating other known data about the user identifier (e.g., evaluate stored data for a work address for the user and compare it to GPS information received from the user device associated with the first user 202 a to confirm the first user 202 a is at a work location). For example, the confirmed location 208 (e.g., a building) can be identified by the first user 202 a, such as by identifying a physical address (e.g., a street address) that is associated with the user's workplace. A location confirmation 207 can also include information that identifies the location's type (e.g., a work location), such as if the first user 202 a indicates that the user device 106 a is situated at the user's workplace (e.g., the confirmed location 208). In some implementations, the location can be determined using, e.g., global positioning system (GPS) capabilities of the user device 106 a, location identification based on cell phone towers, or in some other way. In some implementations, identification of the location type can be inferred, e.g., based on other inputs received from the user. In some implementations, information that associates a user identifier to an identified location can be stored in the data store of location associations 132.

At stage 3, for example, the device location engine 124 can process device location data 210 associated with the user device 106 a. Processing can occur, for example, subsequent to confirmation of the location. For example, the device location engine 124 can determine that the user device 106 a is in a vicinity 212 of a confirmed location 208. For example, the user device 106 a can be networked through a WiFi network of the user's workplace, and the vicinity 212 can correspond to an area that includes the range of the WiFi signal. Determining that the user device 106 a is in the vicinity 212 can also include determining that a signal strength included in the device location data 210 meets a minimum threshold signal strength. In some implementations, the vicinity 212 can be defined to exclude areas that are also in common with other WiFi networks, such as at a neighboring building or business. In some implementations, determining the location of a user device associated with the first user 202 a and the vicinity 212 can depend on a WiFi signal that has a strong or stronger signal in relation to other WiFi signals in a same area. In some implementations, device location information, including associations with confirmed locations, can be stored in the data store of device locations 134.

At stage 4, for example, the location determination engine 126 can use location information 214 processed from the user device 106 a to confirm that a sufficient number of occurrences have been identified of a presence of a device associated with the user identifier in the vicinity 212 of the confirmed location 208. The location determination engine 126 can also receive or determine environment characteristics 216 in association with the location information 214, e.g., a common wireless network 217 having a particular network identifier (e.g., a WiFi with SSID identifier “A”). For example, the sufficient number of occurrences (e.g., 10) can indicate, e.g., with a relative degree of certainty, that the user's confirmed location 208 is correct, in part because of repeated use of the same wireless network 217. In some implementations, the environment characteristics 216 can include other characteristics (e.g., in addition to WiFi-related information) associated with the confirmed location 208 and the vicinity 212. The other characteristics can include, for example, the type of location of the confirmed location 208 and surrounding features (e.g., being near a lake, a mall, public transport, or on a ground floor vs. an upper floor in a high-rise building). In some implementations, information indicating that a user has been confirmed to be present at a particular location (e.g., the confirmed location 208) can be stored in the data store of confirmed locations 136.

At stage 5, for example, the location determination engine 126 can store the one or more characteristics of the environment in association with the confirmed location 208. For example, characteristics stored in the data store of environment characteristics 138 can include information associated with the WiFi or other signal(s), including a signal strength, wireless network identifier information, and other information associated with the environment.

At stage 6, for example, the content management system 110 can receive requests 218 from user devices 106 b associated with the first user 202 a or other users 202 b. The location determination engine 126, for example, can compare the stored one or more characteristics 138 with one or more characteristics of a subsequent request 218 from a user device associated with another user identifier. For example, requests 218 that are received can include characteristics 220 that, among other things, identify the same network identifier (e.g., the particular WiFi SSID “A”) for the wireless network 217 associated with each request 218. In some implementations, the requests 218 can be requests to fill content item slots (e.g., ad slots) on resources (e.g., web pages) displayed on the user devices 106 b.

At stage 7, for example, when the comparing indicates a match, the location determination engine 126 can associate the confirmed location 208 with the subsequent request 218. For example, characteristics 220 associated with each of the requests 218 can be compared to the environment characteristics 216 stored in the environment characteristics 138 that are stored in association with the confirmed location 208. When matches are detected by the location determination engine 126, for example, each corresponding request 218 can be associated 222 with the confirmed location 208. Information for the matches can be stored, for example, in the data store of confirmed locations 136. This information can be used, for example, when selecting content to be provided in response to the requests 218. For example, a user may be an employee of a given company with a physical brick-and-mortar location (e.g., a salesman at a car dealership). The user may be confirmed as being associated with the physical brick-and-mortar location, such as after a series of occurrences in which the user has used a WiFi network at the brick-and-mortar location. Environment information associated with the brick-and-mortar location can be stored, e.g., in the data store of environment characteristics 138. Subsequently, when other users access the same WiFi network, the other users can be associated with having a confirmed location 208 associated with the brick-and-mortar location. Determining this association can be useful, for example, in situations where the brick-and-mortar location may have insufficient GPS coverage, such as inside a large building or in a mall. In some implementations, content (e.g., an advertisement for the car dealership) can be selected based on the determining that the other users are in proximity to the confirmed location 208.

FIG. 3 is a flowchart of an example process 300 for associating received requests from users with a particular confirmed location of a user identifier. In some implementations, the content management system 110 can perform steps of the process 300 using instructions that are executed by one or more processors. FIGS. 1-2 are used to provide example structures for performing the steps of the process 300.

A user identifier associated with a user is received (302). As an example, the location association engine 122 can identify an identifier associated with the first user 202 a when user identification 204 is received, e.g., when the first user 202 a uses an application running on the user device 106 a, a user login service, a social network, or in some other way.

A first confirmation of a location associated with the user identifier is received, including identifying a confirmed location (304). The confirmed location includes a physical address that is associated with the user identifier, and receiving the first confirmation includes receiving a type of location (304). The location association engine 122, for example, can receive the location confirmation 207 that is associated with a user identifier associated with the first user 202 a. For example, the confirmed location 208 (e.g., a building) can be explicitly identified by the first user 202 a, such as by providing a physical address (e.g., a street address) that is associated with the user's current location along with a designation of a type of location (e.g., workplace). The confirmed location can be implicitly provided, such as by comparing previously-stored information with current location information (such as provided by a positioning system or other reference source). Information that associates a user identifier to an identified location can be stored, for example, in the data store of location associations 132.

In some implementations, receiving the first confirmation of the location can include receiving confirmation of a first location, and the type of location can be a work location. For example, the location confirmation 207 can include information that identifies the location's type (e.g., a work location), such as if the first user 202 a indicates that the user device 106 a is situated at the user's workplace (e.g., the confirmed location 208).

In some implementations, receiving the first confirmation of the location can include receiving confirmation of a second different location, and the type of location can be a home location. For example, instead of identifying the work location, the location confirmation 207 can include information that identifies the location's type as a home location for the first user 202 a, e.g., if the confirmed location 208 is the user's home.

In some implementations, associating the confirmed location can further include using the confirmed location for selecting content to provide in response to the subsequent request. The content management system 110, for example, can select content items (e.g., advertisements) responsive to requests for content that are received from the user device 106 a. Selecting content can be based, at least in part, on the confirmed location 208 associated with a user identifier associated with the first user 202 a.

Subsequent to receiving the first confirmation, location data associated with a user device associated with the user identifier is processed (306). The device location engine 124, for example, can process the device location data 210 associated with the user device 106 a, e.g., subsequent to user identification 204 and location confirmation 207. Processing the device location data 210 can include determining, for example, that the user device 106 a is networked through the wireless network 217 of the user's workplace, e.g., within the vicinity 212 that corresponds to an area that includes the range of a WiFi signal associated with the wireless network 217.

A second confirmation is performed, including confirming, based on the processing, that a sufficient number of occurrences have been identified of a presence of a device associated with the user identifier in the vicinity of the confirmed location, including determining one or more characteristics of an environment accessed by the user in association with a presence at a confirmed location (308). As an example, the location determination engine 126 can use location information 214 processed from the user device 106 a to confirm that a sufficient number of occurrences have been identified of a presence of the first user 202 a in the vicinity 212 of the confirmed location 208. There can be a separate set of location information 214 that is received, for example, each time the first user 202 a is in the vicinity 212.

One or more characteristics of an environment accessed by the user are determined in association with a presence at a confirmed location (309). For example, the location determination engine 126 can also receive or determine environment characteristics 216 in association with the location information 214, e.g., a common wireless network 217 having network identifier or SSID identifier “A”. Each of the occurrences can be used to indicate, e.g., that the user's confirmed location 208 is correct, in part because of repeated use of the same wireless network 217. In some implementations, information indicating that a user has been confirmed to be present at a particular location (e.g., the confirmed location 208) can be stored in the data store of confirmed locations 136.

In some implementations, confirming a sufficient number of occurrences can include determining a plurality of occurrences of the presence of the user are received from a location in the vicinity to the confirmed location based on a network identifier for a wireless network and one or more network signal quality metrics associated with a received request. For example, the location determination engine 126 can track and count the number of times that location information 214 indicates that the first user 202 a has used the wireless network 217 with a signal quality metric (e.g., signal strength) above a pre-determined level, and the count can be used to confirm the sufficient number of occurrences. In some implementations, the network identifier can be a wireless network identifier information. In some implementations, network identifiers can include particular SSIDs, media access control (MAC) addresses, or other identifiers.

In some implementations, the second confirmation can include determining signal strength of a wireless signal associated with a signal that includes the location data, comparing the signal strength to a threshold, and when the signal strength exceeds the threshold, a network identifier for the wireless network associated with wireless signal can be stored in association with the confirmed location. For example, the location determination engine 126 can determine if the signal strength identified in the characteristics 220 is above a pre-determined threshold, e.g., that can indicate by a relative certainty that the signal is associated with the wireless network 217. When the signal strength exceeds the threshold for a given request 218, for example, the SSID “A” can be stored in association with the request.

The characteristics of the environment are stored in association with the confirmed location (310). As an example, the location determination engine 126 can store the environment characteristics 216, in association with the confirmed location 208, in the data store of environment characteristics 138. The information that is stored can include, for example, information associated with a WiFi network or other signal(s), including a signal strength, wireless network identifier information, and other information associated with the environment.

Subsequent to the storing, requests are received from other users, including evaluating one or more characteristics of a given subsequent request and comparing the one or more characteristics of the subsequent request with the stored characteristics (312). The content management system 110, for example, can receive requests 218 from user devices 106 b associated with other users 202 b. The location determination engine 126, for example, can evaluate one or more characteristics 220 of a given subsequent request 218 and compare the one or more characteristics 220 with the environment characteristics 216 (of the confirmed location 208) that are stored in the data store of environment characteristics 138. For example, some or all of the requests 218 that are received can include characteristics 220 that identify, among other things, the same network identifier (e.g., the particular WiFi SSID “A”) for the wireless network 217 associated with each request 218.

When the comparing indicates a match, the confirmed location is associated with the subsequent request (314). For example, when the location determination engine 126 determines that a match exists between the characteristics 220 and the environment characteristics 216 for a particular request 218, the location determination engine 126 can associate the confirmed location 208 with the particular request 218. Information for the matches can be stored, for example, in the data store of confirmed locations 136. This information can be used, for example, when selecting content to be provided in response to the requests 218. For example, the content management system 110 can select content items (e.g., advertisements, offers, coupons, maps) that can be selected, at least in part, based on the confirmed location 208 associated with the requests 218.

In some implementations, associating the confirmed location with the subsequent request can include identifying an entity (e.g., a business) associating with the confirmed location and associating the identified entity with the subsequent request. For example, the content management system 110 can determine the name of the business based on the confirmed location 208 and can use the information in selecting content that is more relevant to the other users 202 b.

In some implementations, the entity can be a brick-and-mortar location associated with the entity. For example, the entity can be a physical building (or area) among one or more buildings (or areas) that are associated with a company, a business, a location, a municipality, or some other group or controlling interest.

In other implementations, multiple processors and/or multiple buses may be used, as appropriate, along with multiple memories and types of memory. Also, multiple computing devices 400 may be connected, with each device providing portions of the necessary operations (e.g., as a server bank, a group of blade servers, or a multi-processor system).

The memory 404 stores information within the computing device 400. In one implementation, the memory 404 is a computer-readable medium. In one implementation, the memory 404 is a volatile memory unit or units. In another implementation, the memory 404 is a non-volatile memory unit or units.

In one implementation, a computer program product is tangibly embodied in an information carrier. The computer program product contains instructions that, when executed, perform one or more methods, such as those described above. The information carrier is a computer- or machine-readable medium, such as the memory 404, the storage device 406, or memory on processor 402.

The high-speed controller 408 manages bandwidth-intensive operations for the computing device 400, while the low-speed controller 412 manages lower bandwidth-intensive operations. Such allocation of duties is an example only. In one implementation, the high-speed controller 408 is coupled to memory 404, display 416 (e.g., through a graphics processor or accelerator), and to high-speed expansion ports 410, which may accept various expansion cards (not shown). In the implementation, low-speed controller 412 is coupled to storage device 406 and low-speed bus 414. The low-speed bus 414 (e.g., a low-speed expansion port), which may include various communication ports (e.g., USB, Bluetooth®, Ethernet, wireless Ethernet), may be coupled to one or more input/output devices, such as a keyboard, a pointing device, a scanner, or a networking device such as a switch or router, e.g., through a network adapter.

The computing device 400 may be implemented in a number of different forms, as shown in the figure. For example, it may be implemented as a standard server 420, or multiple times in a group of such servers. It may also be implemented as part of a rack server system 424. In addition, it may be implemented in a personal computer such as a laptop computer 422. Alternatively, components from computing device 400 may be combined with other components in a mobile device (not shown), such as computing device 450. Each of such devices may contain one or more of computing devices 400, 450, and an entire system may be made up of multiple computing devices 400, 450 communicating with each other.

Computing device 450 includes a processor 452, memory 464, an input/output device such as a display 454, a communication interface 466, and a transceiver 468, among other components. The computing device 450 may also be provided with a storage device, such as a micro-drive or other device, to provide additional storage. Each of the components 450, 452, 464, 454, 466, and 468, are interconnected using various buses, and several of the components may be mounted on a common motherboard or in other manners as appropriate.

The processor 452 can process instructions for execution within the computing device 450, including instructions stored in the memory 464. The processor may also include separate analog and digital processors. The processor may provide, for example, for coordination of the other components of the computing device 450, such as control of user interfaces, applications run by computing device 450, and wireless communication by computing device 450.

Processor 452 may communicate with a user through control interface 458 and display interface 456 coupled to a display 454. The display 454 may be, for example, a TFT LCD display or an OLED display, or other appropriate display technology. The display interface 456 may comprise appropriate circuitry for driving the display 454 to present graphical and other information to a user. The control interface 458 may receive commands from a user and convert them for submission to the processor 452. In addition, an external interface 462 may be provided in communication with processor 452, so as to enable near area communication of computing device 450 with other devices. External interface 462 may provide, for example, for wired communication (e.g., via a docking procedure) or for wireless communication (e.g., via Bluetooth® or other such technologies).

The memory 464 stores information within the computing device 450. In one implementation, the memory 464 is a computer-readable medium.

Specifically, expansion memory 474 may include instructions to carry out or supplement the processes described above, and may include secure information also. Thus, for example, expansion memory 474 may be provide as a security module for computing device 450, and may be programmed with instructions that permit secure use of computing device 450. In addition, secure applications may be provided via the SIM cards, along with additional information, such as placing identifying information on the SIM card in a non-hackable manner.

Communication interface 466 may provide for communications under various modes or protocols, such as GSM voice calls, SMS, EMS, or MMS messaging, CDMA, TDMA, PDC, WCDMA, CDMA2000, or GPRS, among others. Such communication may occur, for example, through transceiver 468 (e.g., a radio-frequency transceiver). In addition, short-range communication may occur, such as using a Bluetooth®, WiFi, or other such transceiver (not shown). In addition, GPS receiver module 470 may provide additional wireless data to computing device 450, which may be used as appropriate by applications running on computing device 450.

Computing device 450 may also communicate audibly using audio codec 460, which may receive spoken information from a user and convert it to usable digital information. Audio codec 460 may likewise generate audible sound for a user, such as through a speaker, e.g., in a handset of computing device 450. Such sound may include sound from voice telephone calls, may include recorded sound (e.g., voice messages, music files, etc.) and may also include sound generated by applications operating on computing device 450.

The computing device 450 may be implemented in a number of different forms, as shown in the figure. For example, it may be implemented as a cellular telephone 480. It may also be implemented as part of a smartphone 482, personal digital assistant, or other mobile device.
